ZigZag_ND_local
Procedure ZigZag_ND_local(Re, Pr, alpha: Nusselt, f) returns the local (averaged over a unit cell) Nusselt number and friction factor associated with flow through a zig-zag channel. Entrance effects are not included - these are local in that they are at a particular location.
Inputs:
Re - Reynolds number
Pr - Prandtl number
alpha - angle [degree] or [radian]
Outputs:
Nusselt - local Nusselt number
f - local friction factor
Notes:
This procedure uses the correlation from Moisseytsev et al. (2020)
Example:
$UnitSystem SI Mass J K Pa Radian
alpha=50 [degree]*convert(degree,rad)
Re=1e5
Pr=2
Call zigzag_nd_local(Re, Pr, alpha: Nusselt, f)
{Solution:
Nusselt = 388.5
f = 0.0353
